Title: Environmentally-friendly product for gritting during the winter and for aerating the soil
Inventor: HARDEBECK KARL
IPC: C09K3/18
Filed: 1984-06-02
Abstract: The object of the present invention is 1. to provide a gritting product for roads which are covered in black ice or with a slippery layer of snow, which reduces the danger of sliding, dissolves ice and snow, does not leave any staining residues, whose mixtures do not undergo separation, which is non-corrosive, does not weaken organs of humans and animals and does not have adverse effects on the vegetation; 2. to provide a gritting agent for gritting during the winter and for aerating the soil, which, when used for aerating the soil, has a loosening and fertilising effect on the soil and is beneficial to vegetation. This object is achieved essentially by a gritting agent based on mixtures of particulate material and of compounds which have a fertilising and melting-point-lowering effect, composed of Eifel lava having a particle size of preferably up to 3 mm and magnesium kainite having a particle size of preferably up to 3mm, the individual particles of these components having sharp edges.

Title: Nozzle for atomising viscous fluids
Inventor: DITTRICH WOLFGANG
IPC: B05B7/04
Filed: 1984-06-25
Abstract: The subject of the invention is a nozzle for atomising viscous fluids. It can be used in particular for atomising viscous solutions of fluid dispersions, emulsions, suspensions and slurries by means of compressed air. The object of the invention consists in the development of a nozzle which ensures a high throughput with the smallest possible requirement of compressed air, avoids disperse systems being destroyed and permits atomisation in the form of a full spray cone of the largest possible diameter. The object is achieved according to the invention by means of a special manner of feeding the fluid to be atomised into an eddy chamber (4). The fluid is forced into the eddy chamber (4) by means of outlet openings (3) which are attached laterally at an angle of 45 DEG ...135 DEG  with respect to the compressed air (8). In the said eddy chamber (4), such an intensive mixing of the fluid with the compressed air takes place that atomisation of the mixture occurs already in the eddy chamber and, on leaving the eddy chamber, the mixture is atomised into extremely fine droplets by expansion despite the high viscosity of the fluid. <IMAGE>

Title: Device for filling, sealing and welding folding plastic bags
Inventor: KROGMANN VIKTOR
IPC: B65B7/06
Filed: 1984-08-01
Abstract: The invention relates to a device for filling, sealing and welding folding plastic bags. To date, the packaging of goods in folding bags and the subsequent sealing and welding of the latter has been regularly carried out in two or three devices which are more or less independent of one another and are normally situated at a distance from one another. The object of the invention is to produce a device which is designed to save space and is able to fill, seal and weld folding bags. The object has been achieved by giving the device a vertical chute with a filling and pressing unit, by arranging a laterally opening reception chamber below the filling and pressing unit to receive the folding bags and by arranging a closing and welding unit which is known per se in the chute at the level of the edge regions of the folding bags.

Title: Monitoring circuit for a universal motor
Inventor: SCHOTTEN HENNO DIPL-ING
IPC: H02H3/02
Filed: 1984-09-07
Abstract: In a monitoring circuit for isolating a circuit for an electrical universal motor 2, 3, having a protection device 1 (which is connected in series in the circuit) and a controllable switch 4, a control voltage U1 which is applied to the latter is evaluated using a further control voltage U2 in a comparison switching device 16 such that the protection device 1 is triggered in the event of a defect. In order to be able to bring about the triggering of the protection device 1 in this case irrespective of the load state of the universal motor 2, 3, a corresponding phantom-series circuit 10, 11 (which supplies the second control voltage U2) is connected in parallel with the series circuit comprising the universal motor 2, 3 and the controllable switch 4. If deviations which are worthy of notice occur between the two control voltages U1 and U2, then a third controllable switch 16 is switched on, which switches an additional current-limiting resistor 17 in parallel with the motor 2, 3. A current which leads to immediate triggering of the protection device 1 then flows via the current-limiting resistor 17. <IMAGE>

Patent DE-3443921-A1 (DE)
Title: Lock
IPC: E05B35/08
Filed: 1984-12-01
Abstract: The invention relates to a lock for doors in places of detention, with change-over blocking tumblers which are mounted vertically adjustably on a bolt shank and, when the bolt shank is pushed out, can be fixed on a holding pin arranged on the lock plate. During the locking operation, the blocking tumblers cooperate respectively with a locking tumbler of a first locking-tumbler set which, like a second locking-tumbler set connected to the locking tumblers of the first set, can be actuated by a key insertable respectively from one side. The lock can be opened only with the key-bit stepping with which it was closed. To make it possible to open the lock by remote control, that is to say draw the bolt head connected to the bolt plate into the lock case, the bolt head is arranged on a bolt plate which can be coupled to the bolt shank via a coupling member and which, in the uncoupled state, is displaceable between its end positions by means of a remotely controllable drive. It is thereby possible to open and close the lock remotely, for example to let authorised individuals pass through, without the need for these individuals to be accompanied by guard personnel having the appropriate key.

Title: Process for treating sludge
Inventor: HENRICH GUENTER DR
IPC: C02F11/13
Filed: 1985-04-12
Abstract: It is known in the treatment of sludge, in particular of sewage sludge, to admix burnt lime to the sludge in order by this means to remove the water from the sludge and make it odour-free and storable. However, this is associated with a high expenditure of time and money. However, according to the invention, these disadvantages are avoided by subjecting the sludge, in particular after a mechanical dewatering, mixed with burnt lime or gypsum, to a thermal drying in a drier.

Title: Friction discs which provide guidance
Inventor: PESCHKE RUDOLF
IPC: F16H13/08
Filed: 1985-07-19
Abstract: In this friction-disc drive with two discs rolling vertically upon one another, friction work is produced by differential speeds at the running surfaces. By altering the diameters and simultaneously displacing two running surfaces with a differential speed relative to the unchanged diameters of two rolling-contact surfaces without a differential speed, the frictional work is reduced by up to half. It is likewise possible, by the application of a friction facing on one running surface, to reduce the contact pressure required for power transmission, the frictional work thereby being reduced further. This improves efficiency and increases the life of the mechanism.

IPC: B62D13/00
Filed: 1985-09-17
Abstract: A circuit arrangement for steering a vehicle is described, having an emergency reset of the steering in the event of power failure. The emergency reset comprises a reversing valve which, in the event of a power failure, deflects the hydraulic oil to an emergency steering valve which is mechanically connected to a deflection lever of the steering and which feeds back the hydraulic oil in a pressureless fashion to the tank for straight-ahead travel. When going round a bend, and in the event of a power failure, the emergency steering valve feeds the hydraulic oil into the steering cylinders in such a way that the latter reset the deflection lever in the direction of straight-ahead travel. The emergency reset according to the invention requires only proven components.

Title: Process for producing a plastic film, and extruder die for carrying out the process
Inventor: ALBRECHT GERD
IPC: B29C48/10
Filed: 1985-11-29
Abstract: A process and an extruder die are described, according to which process, with small technical outlay, for example reprocessed thermoplastic wastes can be processed to produce plastic films. In order to prevent porosities caused by inclusions and relatively small contaminants, a single-component composite film tube is extruded through a simplified multi-layer die. To this end, the melt stream delivered by a screw extruder is branched into partial streams which, after displacement of the melt layers with respect to one another, are merged together again before the die outlet and are extruded in the manner of a composite film.
